【摘要】 基于多体系统动力学理论,在ADAMS/Car中建立基于某车型的主动悬架机械系统模型并装配成整车系统,并在MATLAB/simulink中设计并建立主动悬架PID控制系统,在B级随机路面下,对整车系统进行不同速度下的联合仿真。仿真结果表明:该主动悬架系统在不同速度下能达到明显地减振效果,进而提高整车的平顺性与舒适性,为主动悬架的工程应用提供理论支持。更多还原

【Abstract】 Based on multi -body dynamics,A mechanical system model with active suspension was built in ADAMS/Car,and assembled into a automobile.A PID control system was designed in MATLAB/simulink for active suspension.The co-simulations were carried out based on ADAMS/Car and MATLAB/Simulink in random road rank B with different speed.Simulation result demonstrated that the co-simulation method is effective and feasible;the active suspension system can reduce the mean square roots of the vertical acceleration and the vibration of the vehicle, and improve the ride comfort.It can provide theoretical support for engineering application of active suspension.更多还原
